I think PJ pretty well understands the Estate's feelings toward the films. I feel frustrated that I probably won't live long enough to see the Sil filmed because of what sometimes feels like obtuseness on the part of Christopher Tolkien.

But when I really think about it I can understand his point of view. I don't think Tolkien would have been happy with the films, and I think its very common for writers to be unhappy with the films of their works. In addition for his concern for preserving the integrity of his father's work, CT must also be influenced by how upset he thinks his father would have been made by filmed versions of his works. If you've lost a beloved parent, you don't stop caring about their feelings however hypothetical they might be. CT's relationship to his father's work is a long and complicated one. For example, it seems to me that JRRT was quite anxious to receive his advance for the Hobbit in order to pay for young Christopher's medical bills.

Much as I would love to see the Sil filmed, I don't think its fair to judge Christopher Tolkien for his point of view on the matter. We are plain quiet folk and have no use for adventures. Nasty disturbing uncomfortable things! Make you late for dinner!
